Hi, good afternoon,

Please, could you help me resolve this issue with my wireless connection? This week I successfully installed Ubuntu 16.04 LTS. At first the wireless icon showed. Entering the login and password of my network did not connect. After implementing some suggestions I found on the web the icon disappeared. Placing the laptop close to the modem did not help either. Im now using an Ethernet connection.

Maybe I messed out something trying to find a solution. As most of the replies posted in this forum request users to run some commands, I'm pleased to share the outputs of the ones I used.

Thanks I advance for all of your help and please, let me know if additional information is needed.

Sincerely,

ap-us

eno1 Interface doesn't support scanning.

Hi,
I have installed ubuntu 16.04 in my hp af103ax laptop which has broadcom BCM43142 wlan. Now I have installed latest 6.30.223.271 through synaptic. Also
I have set the security in router to wpa2/aes instead of tkip. But still time to time the wifi is not working. Network manager is showing the wifi is connected but internet
is not working , ping to gateway is getting destination host unreachable. But in the same laptop with win 10 it is working perfectly.

I have dmesg but not showing any such errors.

Please help me here, what I should do to fix it properly.



This is the output of wireless script.It was taken when it was working.


And when not working the output is following:

########## wireless info END ############

I installed linux on my computer/home server. I want to connect the computer to two networks: the raspberry (LAN) and the Internet (ethernet USB - modem Huawei E303).
My problem:
Once everything is correctly, while other times I have an error when I go on any website:
ERR_ADDRESS_UNREACHABLE

and ping e.g google werbsite:
Destination Host Unreachable
It helps to reset network:
sudo service networking restart
What may be the problem? I can not reset the entire connection "networks" because I lose my connection with the raspberry, and this is a very important connection for the server / computer.
I have a configuration in / etc / network / interfaces:
eth0 - Raspberry
eth1 - Internet

I am brand new to Ubuntu-installed under 12 hours ago. Despite extensive attempted help from a friend of mine who is quite the Linux/Ubuntu fanboy, I am unable to properly install drivers for this wireless network card. I have followed video guides and text guides from all over. If you attempt to help me, please try to explain simply so my poor newbie head understands. As the title says I am running Ubuntu 16.04, on the 4.4 Linux kernel.


If you're wondering how I'm posting this without a functioning wireless card-it does function, just not in Ubuntu. I installed Ubuntu alongside my copy of W10.

Hello,

I'm trying to run Edubuntu for a refugee family I've been trying to help using an older Dell Latitude D531, from what I understand I believe it is running a broadcom chip, but nothing I've been able to do has been able to get the wifi working. After trying to install the drivers last night, the wifi indicator light never turned on after several tries and restarts. The strange thing is this morning I noticed the WiFi light on, and it was working just fine, but after the laptop went to sleep and resumed, I havn't been able to get the Wifi indicator light on no matter what, and I'm just really really stumped. I have no idea what I'm doing wrong, I almost feel like I'm going crazy but it was infact working just fine this morning, so I know the driver must be out there.

This is the output for the lspci command:

I've tried:

and

But neither work after a reboot.

Thank you soo much in advance for any help.

Help please, wireless won't work at all... Tried lots of solutions, but nothing's working...

Output after sudo apt-get install bcmwl-kernel-source
and lspci

hello

i was using ubuntu 12.04 for 2 years and i loved it i know it will be dropped soon, a month ago i did upgrade to ubuntu 14 but rolled back because its take much memory

now i have fresh pangolin install ,i installed most of my fav programs but vpn not working !

please help me setup vpn connection , i searched a lot but there no single solution for my problem.

tail -f /var/log/syslog


things i tried already

-adding
[vpn-secrets]

password-flags=0

to /etc/NetworkManager/system-connections

- changing permissions on

/etc/NetworkManager/VPN
&
/etc/NetworkManager/system-connections


- removing and reinstall
ppp package/ network-manager etc


-this http://wiki.ubuntu.com/VPN

Hello,

I'm configuring my sshd_config.

However the man page doesn't make it clear enough, so I'd like to reconfirm:

The ListenAddress (if restricted) would be the default gateway to the router but not the IP it received from the router I believe...?
If it's listening, it can only come from the router gateway, I'd assume, correct?

Stephan

Note: I created a question about the same problem in askubuntu, I hope it's ok to post it here too. If I found a solution in one place I'll past it in the other too, to help others.

I already had a problem with this before, and I was able to get it working using the drivers here: https://github.com/kvalo/ath10k-firm...master/QCA6174.

But after running Ubuntu upgrade (yesterday) I can't get the wifi connection anymore, I created a pastebin with the log of this here: http://pastebin.com/y6Pyj4nm.

I have tried replacing the firmware again both with the kvalo and the FireWalkerX fork, with no result.

I'v also created a pastebin with the output of the wireless-info script recommended, here: http://pastebin.com/Mi6mAqj8.

I replaced my DT-Link wireless router. With the configuration described below I was able to print to my Samsung printer. Since replacing the router, I can no longer print.

My Samsung ML3051ND printer is connected via a switch connected to my new ASUS
RT-N16 wireless router. I have used two approaches to try to print to the printer.

1. "System Settings => Printer => Search
Network Printer. The printer si found and I select the "found"
printer. But then when I try to print to it, the message I get from
cups is either Unable to locate printer or printer not connected.

2. Choose ipp from Printer's report and then select correct driver.
Same result as above.

To try and follow up I ran the following two commands one after the
other. The SAMSUNG ML3050 series was found. Back to 1 and or 2 with the same result.

$ sudo /usr/lib/cups/backend/snmp
$ sudo /usr/lib/cups/backend/dnssd

P.S. The notification area shows a printer icon and queued jobs for the
printer, but if I open the printer dialog, they have already been
deleted.

I'm an ubuntu newbie. I have installed it on a dell D630 laptop, and on an HP Pavilion 23 all-in-one.



The Dell laptop installation went fine, except I had to hunt for drivers for the wifi card (Dell 1390). Once those were found, it worked perfect.

Using the same media to install on the HP All-in-One, the wireless card was found and drivers installed, but when rebooting, it takes 30 minutes for the logon screen to be available. Looking at dmesg, I see the following:



Here is an excerpt from /var/log/system:






sudo lshw -C network output:


iwconfig output:

i am using Ubuntu 14.04 and trying to configure a static IP via terminal... however this is what the interfaces directory presents to me:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
-----------------------

it shows me that instead of showing the current configuration.

any suggestions as to why would be very helpful

Thanks

Hi, I am a complete newbie to Ubuntu and I have a problem with WiFi. This is on a completely new laptop with no Windows or other OS to compare.

This new laptop with Ubuntu has weak WiFi connection and is very sensitive -- even a chair between laptop and router causes the connection to be significantly lower even though the distance is about 1.5 meters. My old Toshiba L300 has no such problem. I also use another WiFi that is few meters from my room and there are some walls in the way but my old Toshiba sees is quite well and it's usable. This new laptop on the other hand connects to it but the connection is so low that even Google takes long to load.

Is this hardware problem or can it be that I just have bad driver?
How can I check what driver do I have?

I have Xubuntu 16.04 and the device is Intel Wireless 3165.

Sorry for my English, I hope it's still understandable.

New laptop, Dell 13 9350 (2016 edition) touchscreen, wifi connects but very weak connection (must be next to router for it to connect).

Have tried all the suggested things I could find, and rolled most back if they didn't work (none did). Also have updated BIOS to latest too. My Wireless info below.

On 4.4.0-28-generic kernel

Any and all help appreciated. Thanks.

Hi,

I installed Lubuntu 16.04 on an Asus Transformer Book T100HA. Unfortunately its Wifi (Broadcom) is not supported yet, so I bought a cheap USB Wifi dongle, a mini USB stick from TP-Link.

At the moment where I put this Wifi dongle in my USB slot it is automatically recognized and it works great.

However, I have problems when I start the laptop. I usually never remove the Wifi dongle, ie it is still in the USB slot when the computer is shut down. If I then start it, no connection to my network is established. What I then have to do is to remove the Wifi dongle. Actually, this gives me a message that ethernet has been disconnected and that I'm offline. If I then put the Wifi dongle back to the USB slot it is recognized and I have a connection within a few seconds. Btw, if I then remove the Wifi dongle again, the message is slightly different from before. Its basically the same, but instead of disconnection from ethernet I get a disconnection from a wireless network.

Any idea what I could try, so I am connected to the wireless network right from the start?

Thanks in advance

I installed a new 16.04 server and spun out a couple of 16.04 containers with LXD. The host server works fine with APT getting IPv4 addresses from DNS. Both containers are getting back IPv6 addresses. I've got a bridge set up on the host and set that bridge to be the default bridge for containers, so both containers are getting DHCP from the same source as the host. No idea what is going on here.

This is what a vanilla container shows:
Err:1 http://archive.ubuntu.com/ubuntu xenial InRelease
Could not connect to fe80::1%eth0:13128 (fe80::1%eth0), connection timed out



I've tried disabling IPv6:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

But all that does is get me address family not supported errors:
Err:3 http://archive.ubuntu.com/ubuntu xenial Release
Something wicked happened resolving 'fe80::1%eth0:13128' (-9 - Address family for hostname not supported)

Oddly the container interfaces on the host show as having an ipv6 address and no ipv4:
vethSQ3Y4C Link encap:Ethernet HWaddr fe:ba:78:7c:e6:a0
inet6 addr: fe80::fcba:78ff:fe7c:e6a0/64 Scope:Link




Yet lxc list clearly shows it has having an IPv4 address and no IPv6:
NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+---------+---------+-----------------------+------+------------+-----------+
| bastion | RUNNING | 10.255.251.167 (eth0) | | PERSISTENT | 0 |

The interface in the container shows both ipv4 and 6:
eth0 Link encap:Ethernet HWaddr 00:16:3e:45:bb:d9
inet addr:10.255.248.86 Bcast:10.255.251.255 Mask:255.255.252.0
inet6 addr: fe80::216:3eff:fe45:bbd9/64 Scope:Link

Hello,
I currently am running Dell optiplex 980 ubuntu server 16.04 and have issues with wireless network card. Simply trying to get it connected to the home network. When i simply try to ping my gateway 192.168.1.1 it returns
my /etc/network/interfaces
I previously had ubuntu server 14.04 and NEVER had a network issue. I know it has to be some new implementation between that version and 16.04 bc it even took my time to figure out they changes the wireless interface name from wlan0 to wlp3s0.
Any relevant help or solutions is appreciated.

i bought a new lenovo laptop last year and I am not able to connect to my home wifi with it.

i found a script to grab the network info :

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wire.../wireless-info && chmod +x wireless-info && ./wireless-info

I have attached the wireless-info.txt file along with this post.

Any help in getting wifi enabled is appreciated.

Note: i have 15.04 installed as dual boot. wifi is not getting enabled. this wireless-info.txt is from a 16.04 live cd. just trying if 16.04 works or not.

I have a qualcomm atheros wifi adapter it looks like:

Network controller [0280]: Qualcomm Atheros QCA6164 802.11ac Wireless Network Adapter [168c:0041] (rev 20)
Subsystem: Lenovo QCA6164 802.11ac Wireless Network Adapter [17aa:3545]
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci

Greetings.
I am with release 12.04 and kernel 3.5

After recent, small updates to the OS and some additional packages, I suddenly cannot access to internet. It worked for years.

I am fully connected with WLAN. I can ping the gateway successfully, as well as 127.0.0.1 (which I do not know what it is).

The file /etc/resolv.conf contains:

nameserver 192.168.7.2
nameserver 192.168.1.241
search eng.myemployer.com

Ping to any of these fails totally.

Can anyone help, please?

Thanks a lot!
